Bacterial motility on a surface: many ways to a common goal.
TLDR
This review focuses mainly on surface motility and makes comparisons to features shared by other surface phenomenon.Abstract:
When free-living bacteria colonize biotic or abiotic surfaces, the resultant changes in physiology and morphology have important consequences on their growth, development, and survival. Surface motility, biofilm formation, fruiting body development, and host invasion are some of the manifestations of functional responses to surface colonization. Bacteria may sense the growth surface either directly through physical contact or indirectly by sensing the proximity of fellow bacteria. Extracellular signals that elicit new gene expression include autoinducers, amino acids, peptides, proteins, and carbohydrates. This review focuses mainly on surface motility and makes comparisons to features shared by other surface phenomenon.read more

γ-Polyglutamic acid (γ-PGA) produced by Bacillus amyloliquefaciens C06 promoting its colonization on fruit surface
TL;DR: In vivo evaluation showed that disruption of gamma-PGA production in C06DeltaywsC impaired its efficiency of colonizing apple surfaces, and it was demonstrated that gamma- PGA was not essential for C06 to form colony on semi-solid surfaces, but was able to improve its colony structure.

Contrasting soil bacterial community structure between the phyla Acidobacteria and Proteobacteria in tropical Southeast Asian and temperate Japanese forests
TL;DR: Topology of UPGMA trees and pattern of NMDS plots among the forests differed among the bacterial groups, suggesting that each bacterial group has adapted and evolved independently in each Forest, indicating limited inter-forest migration and differential movement of bacteria in forest soil.

Blue-light dependent inhibition of twitching motility in Acinetobacter baylyi ADP1: Additive involvement of three BLUF domain-containing proteins
TL;DR: The implementation of all the single knockouts and the triple knockout mutants with any of the three BLUF-domain-encoding genes fully restored the inhibition of twitching motility by blue light that is observed in the wild-type strain, and A. baylyi ADP1 shows a high degree of redundancy in the genes that encodeBLUF-containing photoreceptors.

In silico and Genetic Analyses of Cyclic Lipopeptide Synthetic Gene Clusters in Pseudomonas sp. 11K1
TL;DR: Pseudomonas sp. 11K1 was sequenced and subjected to in silico, mutational, and functional analyses as discussed by the authors, and genome mining identified three potential cyclic lipopeptide biosynthetic clusters, subsequently named brasmycin, braspeptin, and brasamide.

Multidrug-Resistant Salmonella enterica Serovar Typhimurium Isolates Are Resistant to Antibiotics That Influence Their Swimming and Swarming Motility.
TL;DR: Examining several MDR Salmonella isolates determined that many variables influence how antibiotics impact swimming and swarming motility in MDR S. Typhimurium, including antibiotic type, antibiotic concentration, antibiotic resistance gene, and isolate-specific factors.

Biofilm Formation as Microbial Development
TL;DR: The results reviewed in this article indicate that the formation of biofilms serves as a new model system for the study of microbial development.

Biofilms as complex differentiated communities.
TL;DR: It is submitted that complex cell-cell interactions within prokaryotic communities are an ancient characteristic, the development of which was facilitated by the localization of cells at surfaces, which may have provided the protective niche in which attached cells could create a localized homeostatic environment.

Flagellar and twitching motility are necessary for Pseudomonas aeruginosa biofilm development
George A. O'Toole,Roberto Kolter +1 more
TL;DR: The isolation and characterization of mutants of Pseudomonas aeruginosa PA14 defective in the initiation of biofilm formation on an abiotic surface, polyvinylchloride (PVC) plastic are reported and evidence that microcolonies form by aggregation of cells present in the monolayer is presented.
